Only by jury rigging it ... the normal insulation is designed to vent the heat outside.
But it can be used as a form of electric heater.
If one's home is already heated, one can use a ceramic infrared heater for maintaining the heat. The ceramic infrared heater prevents the temperature of the room from dropping.
a blow dryer
YES!!!!YES you can. It has nothing to do with the hot water, unless you have a gas dryer and you have shut off the gas.
radiation
The heat from the hair dryer acts like hair straightners i suppose?
DO NOT USE YOUR GAS OVEN TO HEAT YOUR HOME. prolonged use of an open oven in a closed home burns up oxygen and creates lethal carbon monoxide.
Electric hot water heater is used to heat cold water for use in winters. Electric hot water heaters heat water faster than the ones which consume fire in order to heat water.
If you mean the two clips glued to the bottom of the window, they can be removed by heating them with a hair-dryer-type heater. I use a heater designed to shrink heat-shrink tubing. Move the heat gun around as you heat them so the heat isn't focused on one spot. The heat softens the glue. Once nice and warm, gently prying with a wooden stick will allow the clip to be removed. I then use a single-edge razor blade to finish removing the glue residue.
electric iron , electric toaster, electric water heater, electric geyser
When a car runs, it produces heat as a wasted product. This heat is then used to heat up air and blow it at you. This heat will be created even when the heater is off, so using the heater should not lower gas mileage.
A car heater taps off engine heat. If you aren't driving, then the engine is cold and there's no heat for the car heater to use.
